Bases: object

The piecewise-linear interpolation strategy, with polynomial at \(\left|a\right| < 1\).

\[\sigma_{sb} (\vec{\alpha}) = \sigma_{sb}^0(\vec{\alpha}) + \underbrace{\sum_{p \in \text{Syst}} I_\text{lin.} (\alpha_p; \sigma_{sb}^0, \sigma_{psb}^+, \sigma_{psb}^-)}_\text{deltas to calculate}\]

__init__(histogramssets, subscribe=True)
